Objective To investigate the expressions of TRIM59,Twist and E-cadherin in hepatocellular carcinoma and their clinical significance. Methods The expressions of TRIM59,Twist and E-cadherin protein were tested by immunohistochemistry in 80 cases of hepatocellular carcinomas and the adjacent paracancerous tissues. Results The positive rate of TRIM59 in hepatocellular carcinoma was significantly higher than that in the adjacent paracancerous tissue(76.3%vs. 8.0%,P<0.05). Significant difference was also observed in the expres-sion rate of Twist between the hepatocellular carcinomas and the paracancerous tissue(66.3%vs. 6.0%,P<0.05). The positive rate of E-cadherin in hepatocellular carcinoma was significantly lower than that in the adjacent para-cancerous tissue(27.5%vs. 90.0%,P<0.05). The differences of the expression of TRIM59 in hepatocellular carci-noma of pathological grading,tumor differentiation,vascular invasion and clinical TNM stage were significant(P<0.05). The differences of the expression of Twist in hepatocellular carcinoma of pathological grading ,differentia-tion,vascular invasion and clinical TNM stage was also significant(P<0.05,respectively). The differences of the expression of E-cadherin in hepatocellular carcinoma of pathological grading,differentiation,vascular invasion and clinical TNM stage were also significant(P<0.05,respectively). Significantly positive correlation was also found between TRIM59 and Twist by using spearman correlation analysis(P<0.05). Negative correlations were observed between TRIM59 and E-cadherin(P < 0.05),and between Twist and E-cadherin(P < 0.05). Survival analysis showed that TRIM59 expression was an independent prognostic factor in hepatocellular carcinoma. Conclusion TRIM59,Twist and E-cadherin protein expression might be associated with the development,invasion,and metas-tasis of hepatocellular carcinoma. TRIM59 may become a new target gene for the treatment of human hepatocellular carcinoma.

Objective To evaluate the application of endoscopic needle- knife precut sphincterotomy (PST) in treating acute suppurative cholangitis. Methods After failure of routine papillary intubation during encoscopic retrograde cholangio-pancreatography (ERCP) in papillary incarcerated stone or inflammatory stenosis cases, needle-knife PST was applied to find the lower opening of the common bile duct. After that, routine papillary sphincterotomy or balloon dilation followed. Then net basket for stone extraction and nasobiliary catheter for drainage were made. Results Eleven of the 12 cases′ stones were extracted successfully, the success rate was 91.7%. In the 11 cases, 5 cases′ incarcerated stones dropped into duodenum automatically after sphincterotomy; 9 cases′ stones were extracted successfully in one treatment while 2 cases′ stones were extracted secondarily after stents were implanted; 1 case′s stone could not be extracted and need surgical treatment after nasobiliary catheter drainage because of stenosis of the lower part of the common bile duct. There was no dead case in all the cases. Conclusions Acute suppurative cholangitis patients, who have papillary incarcerated stones or inflammatory stenosis, can receive more efficacious diagnosis and treatment by applying PST when routine endoscopic papillary intubation fails. PST is an important endoscopic treatment for acute calculous suppurative cholangitis
